[A general survey carried out on several brands of frozen prawn products has shown that along with the standard plate count (SPC), the numbers of pathogenic organisms like Escherichia coli, enterococci and coagulase positive staphylococci have also to be taken into consideration for the evaluation of the quality of these products. No correlation could be established between the total plate coun...

Molecular determination of carriage of the mecA locus in coagulase negative staphylococci in screening swabs from patients in an intensive care unit Staphylococci are important nosocomial pathogens, which are easily transmitted from patient to patient, and there is concern over the recent emergence of antibiotic resistance to the β lactam class of antimicrobial drugs, particularly within methic...

Staphylococcus chromogenes is one of the main coagulase-negative staphylococci isolated from mastitis of dairy cows. We describe S. chromogenes isolates that can clot plasma. Since the main pathogen causing mastitis is coagulase-positive Staphylococcus aureus, the coagulase-positive phenotype of S. chromogenes described here can easily lead to misidentification.

BMS-247243, a novel cephalosporin inhibitory for methicillin-resistant staphylococci, primarily has activity against gram-positive bacteria. The activities of BMS-247243, cefotaxime, and ceftriaxone against streptococci and Streptococcus pneumoniae were similar. BMS-247243 inhibits Enterococcus faecalis but not Enterococcus faecium. BMS-247243 also inhibits many inherently vancomycin-resistant ...

licensed dairy farms in the central region of Fars province were randomly selected in order to participate in aseasonal prevalence study. A cross-sectional study was designed to determine prevalence at cow and quarterlevel based on clinical signs for clinical mastitis and indirect tests for subclinical mastitis. 6180 quarters from1545 dairy cows were tested by clinical examination and Californi...

The in vitro activity of TR-700 (torezolid) was evaluated against a collection of 660 staphylococcal blood isolates. TR-700 showed excellent activity against all the staphylococci tested. The MIC(50) and MIC(90) values of TR-700, linezolid, daptomycin, and vancomycin against methicillin-resistant Staphylococcus aureus (MRSA) isolates were 0.25 and 0.5, 2 and 4, 0.5 and 0.5, and 1 and 2 microg/m...

The doripenem MICs at which 90% of the tested strains were inhibited ranged from 0.03 to 1 microg/ml for 10 species of Enterobacteriaceae (n = 351), from 0.03 to 0.12 microg/ml for oxacillin-susceptible staphylococci (n = 119), from 4 to 32 microg/ml for oxacillin-resistant staphylococci (n = 64), from < or =0.008 to 0.06 microg/ml for penicillin-susceptible streptococci (n = 132), and from 1 t...

A rapid colorimetric method for the presumptive identification of group A streptococci and enterococci based upon pyroglutamyl aminopeptidase activity is described. Of 76 group A streptococcal isolates from primary plates, 83 gave positive reactions, and the remaining 7 were positive on retesting in pure culture. Of the 31 enterococcal isolates tested, all gave positive reactions. Despite occas...

The following organisms have shown in vitro sensitivity to DBLTM Cefotaxime Sodium for Injection. Gram-positive: Staphylococci spp, including coagulase-positive, coagulase-negative and penicillinase-producing strains. Streptococci spp, including &beta;-haemolytic and other streptococci such as Streptococcus mitis (viridans), Streptococcus pneumoniae. (Many strains of enterococci, e.g. Streptoco...
